c + 9 - 3(c - 10) > 1
We're going to treat this like a regular algebraic equation, thus most algebraic rules and properties apply.
First, apply distributive property.
c + 9 <u>- 3c + 30</u> > 1 (two - signs cancel out, creating a + sign.)
Combine like terms.
<u>-2c + 39</u> > 1
Subtract 39 from both sides.
-2c > <u>-38</u>
Divide both sides by -2.
<u>c < 19</u> (Because we're dividing by a negative number, the sign gets swapped.)
<h3>Your answer is c < 19.</h3>
